I need freeware software realted to helpdesk management software. when a new call come i should log in my s\w and same way i should track the call is it finish or not and h\w & s\w inventory i should do in that software.

Well, I've seen a number of write-your-own sollutions in the past, but they weren't great and they needed some work.

What I saw in the past were either Access Databases with an Access front-end or some generic database run on a webserver, with ASP/CFM pages to read/modify the database.

Interesting questions to ask are:
1. How much time are you and your employer willing to put into making a roll-your-own package work?
2. How many calls will you be handling a day?
3. What kind of information do you want to entered with every case? Would you like work logs to be entered? And how about final sollutions, so you can look back in the future?
4. Must the tool be absolutely free?

Well, he did say he wanted a free sollution, so getting someone to write it for them won't work...

But I don't really see another way around it... Any sollution requires time and money. Either you:
A) Download some free software and put time into modifying it
B) Get someone to write you a simple piece of software
C) Buy a commercial product...

I've used both request-tracker and mantis quite successfully for help desks.

I'm not sure what "and h\w & s\w inventory i should do in that software." means. A hardware and software inventory system is a separate program from a ticket tracker. Here are some options for that http://software.newsforge.com/artic...9206&tid=91

@Salvaico:
Some tools used for helpdesks actually have the option of integrating a CMDB into them. ARS Remedy for example is used by my current client to keep track of incidents/problems/changes and includes the hardware and application CMDB.
